Chewing Gum Overwhelming Mexico City's Sidewalks

The sidewalks of Mexico City are being overwhelmed by gum, spit out and ground into the pavement to the tune of 70 pieces every three feet. So the city's point man in keeping public spaces clean, Ricardo Jaral, has a message for those of you who would toss your flavorless chew in the street:

When you finish chewing a piece of gum, you either have to put in a piece of paper and deposit it in a trash receptacle, or swallow it.

Isn't that bad for you? Jaral says nope:

I've always swallowed my gum, and it's never done me any harm.

At least you'll still be allowed to pop a piece on a whim: While you're now allowed to chew in Singapore, you can only get so-called therapeutic gum from pharmacies after showing ID.
